Schlagwort: Preserving Cities From Climate Change

Today I found a very interesting map in the WWW, how Earth will look like, when average temperatures rise about 4 degrees Celsius or 7.4 degrees Fahrenheit. Let’s think big (theoretically) for a moment:

In the future cities and agricultural zones will be located in Canada, Alaska, Siberia, West Greenland and West Antarctica. Only a little bit remains in West Africa and West Australia. The arctic passage will be the most important trade route. Todays tropical and temperate zones will change to deserts: South Europe and South America will be deserts, USA, China and India will also be deserts, the Alps and other mountain regions will be ice free. Northern Europe, England and Russia will be the last remains of the historically relevant political and military powers. Raising superpowers like China and India will vanish as fast as they came. Canada will obviously not survive as a nation and will become somehow ‚New America‘.

For anyone who reads this map it becomes very fast completely clear, why India and China are strengthening their activities in space exploration, nuclear power and antarctic research. It also becomes clear why Russia is currently arming and pile up nuclear weapons as fast as they can. This behavior is very rational from the point of view of such a climatic scenario in some decades.

– A preleminary business plan for building simple fusion energy plants and space ships

If You are interested in pure fusion detonations for civilian energy provision purposes You may be right on my blog. I like to write about technology, that has generally the power to be bad in the wrong hands and to be good in the right hands. I write about ethics and theology, philosophy and new Stellar Ecology a generalization of planetary ecology that gives mankind a very simple but also very beautiful sense in the universe. I write about interstellar travel and the preconditions for that. Mostly I write in German – just because it is much easier to me. In this article I will write about the organizational problems and the main development risks of a pure fusion energy development program.

A Science Fiction Story of Today

Along with the sun thermonuclear detonators are the only way to produce relevant amounts of fusion energy. All other methods ever tested – if they provide fusion energy at all – consume much more energy for igniting the fusion reaction than they release. So, if mankind plans to use fusion energy for civilian purposes within the next decades, it has eventually to accept, that there is only one foreseeable, realistic and practical way: using smaller hydrogen detonators in power plants, within huge underground vessels, where fusion explosions heat up a medium – similar to the explosions in a motorcar [1]. There is one big problem: all of todays hydrogen fusion detonators are ignited by plutonium-239 fission bombs, the so called primaries. These fission bombs produce highly radioactive, lethal fission products like iodine-131, strontium-90, caesium-137 [2]. It is exactly the same problem as with our fission reactors. The fission products contaminate humans, animals and plants and cause radiation sickness and cancer. This is why I have started to write about thermonuclear fusion energy plants on the moon or nuclear pulse space ships with home bases on the lunar surface. You can read about it here [3][4] if You are interested in that topic. With this kind of machines, based far away from earth’s biosphere, it would be possible for mankind to use fusion energy by todays means without any potential side effect for earths environment and human society. But can a fusion detonator only be ignited by a fission bomb? Is there another non-nuclear way of ignition? Is it possible to build a 100% clean detonator, the pure fusion bomb?
